Wind Power Chart

The power generated from a windmill depends on both the wind speed
and the size of the blades.

For example, if the average wind speed at the site is 12 mph,
a small 100 watt generator will turn out only 11 kWh, but a 2,000
watt generator will produce 160 kWh and a 10,000 watt generator
will product 730 kWh.
